Concerning...Severe potential...Watch likely Valid 160313Z - 160415Z Probability of Watch Issuance...95 percent SUMMARY...Storms will exit WW309 in the next 1-2 hours with a continued risk primarily for damaging winds hail, and a tornado or two. A new watch is needed prior to 05z. DISCUSSION...Ongoing mixed-mode cluster of supercells and short bowing segments across portions of North Texas have begun to accelerate southeastward over the last 30 min. Additional storms moving in from southern Oklahoma should aid in cold pool acceleration over the next hour. Approaching the eastern edge of WW309, these storms should continue to move into an unstable and strongly sheared environment with 3000-4000 J/kg of MLCAPE and 50-60 kt of effective shear. Given the upscale growth over the last hour, damaging winds and isolated hail are expected to be the primary threat into the overnight hours. However, backed low-level flow along and effective warm front/outflow boundary may still support a risk for a tornado or two this evening. A new weather watch is likely needed prior to 0500z across portions of Northeast TX, southeastern OK and northwestern LA. ..Lyons/Grams.. 06/16/2023 ...Please see www.spc.noaa.gov for graphic product...
